Description

Technical Field

[0001] The utility model relates to the technical field of mother and baby products, and particularly relates to a temperature detecting device for a milk shaker and a milk shaker with the same. Background Art

[0002] What is provided in this part is only background information related to the present application to facilitate those skilled in the art to understand the present application more thoroughly and accurately. It is not necessarily prior art.

[0003] When feeding milk powder to a baby, an appropriate amount of warm water needs to be added to the milk bottle, and then an appropriate amount of milk powder is added. After covering the nipple, the milk bottle is rotated back and forth left and right with both hands to shake and dissolve the milk powder in the milk bottle. Such an operation is not only time-consuming and laborious, but also cannot ensure the full dissolution of the milk powder. Therefore, lumps often form on the inner wall of the milk bottle, resulting in waste. In addition, this manual shaking method is difficult to ensure the uniformity of milk shaking, and it is easy to generate bubbles in the milk in the milk bottle, causing the baby who drinks the milk to easily have flatulence, hiccups and other conditions.

[0004] To solve the above problems, an automatic milk shaker that can automatically shake the milk bottle appears on the market, thus releasing the user's hands, saving time and effort, and at the same time enabling the milk powder to be fully dissolved. At present, most automatic milk shakers use a non-contact temperature detection method to detect the temperature of the milk liquid in the milk bottle, such as infrared temperature detection. However, most infrared probes are externally exposed, and they are easily contaminated, thereby affecting the temperature detection accuracy. Summary of the Utility Model

[0053] Embodiment 1

[0054] Referring to Figures 1-4 , this utility model provides a temperature detection device 1 for a milk shaker, which includes a milk bottle basket 11, a support plate 12, a protective cover assembly 13, and an infrared probe 14 arranged in sequence from top to bottom. The milk bottle basket 11 is provided with a receiving cavity 111 for placing a milk bottle, and a first through hole 112 communicating with the receiving cavity 111 is opened at the bottom of the milk bottle basket 11; the support plate 12 is arranged at the bottom of the milk bottle basket 11 and supported by the milk bottle basket 11, and a second through hole 121 communicating with the first through hole 112 is opened on the support plate 12; the infrared probe 14 is arranged below the support plate 12, and the infrared rays emitted by the infrared probe 14 can sequentially pass through the second through hole 121 and the first through hole 112 and irradiate on the bottom of the milk bottle to achieve temperature detection; the protective cover assembly 13 includes a protective cover 131 that can rotate and at least partially shield the infrared probe 14 and a driving assembly for driving the protective cover 131 to rotate.
